Simulation of an explosion in GEO (after 2 days)

What happens after an explosion in space? A geostationary satellite has a velocity of about 3 kms/second (11,000 kms/hour). The fragments are ejected with a much lower velocity and thus stay close to the initial orbit. However, some will travel a bit faster and others a bit slower. Within a few days the debris cloud will form a diffuse ring at 36,000 km altitude around the Earth.
